The second biggest butter brand in the U.S., Kerrygold, proudly markets itself as
“Pure Irish Butter from Grass-Fed Cows.” Sounds healthy, right? But here’s the reality:
these cows are often finished on GMO corn, soy, and grains before milking.
That means the “grass-fed” claim is misleading. Big butter is cashing in on the health halo while
feeding cows in the industrial corn-and-soy system.
The Corn & Soyconomy
This practice isn’t new — it’s part of the larger corn and soyconomy that dominates
industrial dairy. Farmers supplement pasture diets with cheap GMO grains to increase production and profits.
Unfortunately, it also dilutes the nutritional quality of the butter you think is “pure.”
Why 100% Grass-Fed Butter Matters
If you want truly nutrient-dense butter, buy local 100% grass-fed and grass-finished butter.
Benefits of real grass-fed butter include:
- High in healthy omega-3 fatty acids and CLA (conjugated linoleic acid)
- Rich in fat-soluble vitamins: A, D, E, and K2
- Contains antioxidants like beta-carotene and vitamin E
- Better for metabolic and heart health than grain-fed butter
Make Your Own Grass-Fed Butter
Making butter at home is easier than most people think. All you need is:
- Fresh cream from 100% grass-fed cows
- A bowl and hand mixer (or food processor)
- Salt (optional)
Steps:
- Pour fresh cream into a bowl.
- Whip cream on high until it separates into butter and buttermilk.
- Strain out the buttermilk and rinse the butter under cold water.
- Add salt if desired and store in a clean container.
The result is rich, creamy, golden butter packed with the full nutritional benefits of grass-fed cows.
Unlike industrial butter brands, homemade or truly grass-fed butter gives you the vitamins, healthy fats,
and taste that nature intended.
Bottom Line
Kerrygold may market itself as “pure Irish” and “grass-fed,” but the reality is cows are often finished on GMO grains.
For real health benefits, choose local, 100% grass-fed and grass-finished butter, or make your own at home.
Your body—and your taste buds—will thank you.
